Paul,

Here are my thoughts,

1. Austrian (based on the colors). There was a similar one worn in Reichswehr times by the German army.

2. 1.b.Jäger Batl. Funky color green, but there is no other possibility.

3. Colonial Troops, Leutnant.

4. Navy, Lt. zur See. Summer Uniform.

5. Prussian Assistenz-Arzt.

6. Navy, Lt. zur See.
